It shows up as white. My problem there. I told the gd2img program that the data range was -5000 to 5000, when actually there are values as low as -6200. As a result the "missing" values are being set to the last color index in the luts file which is white. I've attached an updated file that now specified that ocean range of pixel values 0-8 to represent -7000 to 0 so that you can use the same color table I provided previously (otherwise, you would have to set the last color index in that lut file to be the dark blue color).
